PIPE-HANGER.

SPEGIFICATION forming part of Letters Patent No. 763,987, dated July 5,1904.

Application filed May 20, 1902.-

To all whom it may concern.-

Be it known that I, HOSEA K. KRIEBEL, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inPipe-Hangers; and I do declare the following to be a art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the figures of reference marked thereon,which form a part of this specification.

The object of this invention is to provide a pipe-supporting device ofthe fewest possible parts and of simple construction designed to besecurely and quickly attached to a beam or other support, freelyaccommodate itself to the longitudinal expansion and contraction of thepipe supported therein, and having a supporting bracket or hook whichmay be readiily applied to the suspending member of the device andconveniently adjusted upon said member to maintain the pipe in theproper positime, as occasion may require, as well as the initialregulation.

The invention consists in an attachingmeans, from which is hung asuspending member adapted to swing laterally and longitudinally of thepipe suspended thereby, and a pipesupporting bracket slidably adjustableon said suspending memberand having a curved retaining-face, which underthe adjustment of the bracket to different elevations will change itsrelation to the pipe, so that the point of support for the pipe willvary with said ad justment, thereby permitting the hanger to freelyadjust itself to the pipe and still maintain the position which its owngravity requires.

In the accompanying drawings, Figure 1 is a view showing the inventionin its preferred form, the attaching means here shown being adaptedespecially for attachment to metal beams of the usual construction. Fig.2 is a front or end view of the hanger as shown ap- V plied in Fig. 1.Fig. 8 is a View showing a modification in which a screw-eye is employedSerial No. 108,269. (No model.)

as the attaching means. Fig. 4 is a perspective View of the adjustablepipe-supporting bracket or hook, and Fig. 5 is a view showing thesuspending member of the hanger.

Referring to the drawings, 1 indicates the beam to which the hanger isafliXed, which in Figs. 1 and 2 is an I-beam of the usual constructionand requires a clamping device to constitute the attaching means for thehanger. The clamping device shown comprises a hooked rod 2, adapted tohook over one side of the base of the I-beam and extend transverselybeneath the base and beyond the same a short distance, and a jaw member3 slidable on said rod member and adapted to be made rigid thereon bymeans of a set-screw 4, which by contact with the rod member binds thetwo parts in adjustable position. The jaw member 3 forms the mainelement of the attaching device and is formed with a depending eye-lug 5for attaching the hanger proper and a slot 6 to receive the base of thebeam. The lower face 7 formed by the slot 6 is flat and has a breadthdue to the intentional enlargement of the embracing part of the jawmember and is therefore adapted to lie on the under side of the base andhold the jaw against movement lengthwise of the beam, while the upperface 8 formed by the slot 6 is inclined to give an inward taper to theslot, so as to insure the firm contact of its lower face with the beamand to accommodate the jaw to beams varying in size and still preservethe tight adjustment of the jaw thereon.

By reason of the above-stated provisions the rod member 2 is adapted tobe bent up from light-weight wrought-iron rods, as the function thereofis merely to hold the jaw member 3 in place upon the beam. This lattermember is preferably cast and forms, together with its cooperating rodmember, a simple, effective, and cheaply-manufactured clampfastening forthe hanger.

The suspending member 9 is a straight rod bent at one end to form anopen eye to hook within the eye 5 of the attaching device and istherefore free to swing in any direction. Upon this suspending member issecured the pipe-supporting bracket or hook 10, which comprises a lightcurved member and a sleeve 10, formed integral therewith at one end,through which sleeve extends the suspending member 9. This sleeve isprovided with a screw-threaded aperture at its rear side to receive aset-screw 11 and is thickened at the aperture by a surrounding boss 10to make the sleeve of the bracket withstand the binding effects of thescrew as well as the strain incident to supporting of the pipe.

By reference to Fig. 1 it will be seen that the hanger will accommodateitself by gravity, so as to maintain the pipe 12 always in a verticalline below the attaching-eye, as will appear from the adjustmentindicated by dotted lines, and the curved supporting-face of the bracketprovides for a change of supporting relation between it and the pipe, sothat the adjustment of the bracket to different elevations will notinterfere with the gravity action of the hanger, as would follow were noprovision made for a point of support for the pipe varying with theadjustment.

From the above it will be readily appreciated that areliable andeffective hanging deviceis produced that may be readily assembled andadjusted as required and one which will not require tedious adjustingoperations or the use of any tool other than a wrench.

W'hat I claim is A pipe-hanger comprising attaching means, a suspendingmember supported therefrom to swing in all directions a pipe supportingbracket slidably adjustable on said suspending member, and having aretaining curved supporting-face adapted to support the pipe atdifferent points thereon as a result of changes in the adjustment,substantially as described and for the purpose set forth.

In testimony whereof I afiix my signature in presence of two witnesses.

HOSEA K. KRIEBEL.
